Weekly Reports Polarstern

The Expedition PS120 Port Stanley - Bremerhaven

The transit cruise from Port Stanley to Bremerhaven will begin on 02.06.2018 and ends on the 29.06.2019.

The cruise is primarily dedicated to the training of students and the preparation and testing of onboard equipment for the upcoming MOSAIC project. During a “floating summer school” an international group of 25 students from 23 countries will be trained in basic techniques of oceanography and remote sensing on a North-South transect from Port Stanley to Bremerhaven (South North Atlantic Training; SoNoAT). The participants will learn how to take samples, how to process them and deal with the accompanying data. The main water masses between the Atlantic and the North Sea will be characterized in terms of their hydrographic features down to a depth of approx. 500 m and more.

In preparation for the following MOSAIC expeditions sensors will be re-calibrated and configured to fit in the board systems. This should assure the functionality during the MOASIC programme, the scholar will be involved in the sensor testing. Additional to the sensors the medical equipment will be inventoried and updated during this cruise.

A further focus during the transit cruise will be physical and chemical measurements as well as detection of mircoplastics and EDNA. In addition, the students will get an introduction into the physics of the climate system, international climate negotiations and data analyses.

A three-day workshop will be held land based to prepare the scholars in application and usage of programming tools and methods.

The floating summer school is a joint project between the Alfred Wegener Institute Helmholtz-Centre for Polar- and Marine Research, the POGO Centre of Excellence, ATLANTOS and the OCEAN TRAINING PORTAL (OTP). It is funded by the Nippon Foundation / POGO Centre of Excellence and the OTP and supported by REKLIM and PORTWIMS (Portugal Twinning for innovation and excellence in marine science and Earth observation).

Polarstern is scheduled to arrive in Bremerhaven on 29.06.2019 and thus ends the expedition PS120.

PS115/2 Weekly Report No. 2 | 10.09. - 16.09.2018

We are ready to start – About Super-Puma, polar bear, kastenlot and OBS

[18. September 2018] 

Monday (10 Sep 18). Shortly after midnight, (the first weekly report with positive news about the start of our research in a few hours has just been sent out) bad news for us: a case of medical emergency, the expedition’s program has to be stopped, we have to steam with full speed back to Longyearbyen – a long way! At 19:45, however, good news from the captain: tomorrow evening we will have a rendezvous with a long-range rescue helicopter NE of Svalbard at 81°N/41°E where a rescue team will take-over our patient.


PS115.2 Wochenbericht Nr. 1 | 03.09. – 09.09.18

From Longyearbyen through the Northeast Passage towards the Siberian Arctic

[10. September 2018] 

Monday (03.09.18). Since early Monday morning “Polarstern“ is anchoring in the Isfjorden, directly off Longyearbyen, and waiting for the new crew and the new group of scientists, who will be embarked for the coming Leg.


PS115.1 Weekly Report No. 4 | 27.08. – 02.09.2018

Last work in the northeastern Greenland Sea in the final week of the cruise

[03. September 2018] 

After returning to the part of the Wandel Sea just off the coast of Kronprins Christian Land, the northeasternmost point of Greenland, station work started including heat flow measurements and sediment sampling (box corer and gravity corer).


PS115.1 – weekly report Nr. 3 | 20.08. – 26.08.2018

Surprising ice conditions favor measurements further north

[27. August 2018] 

The second half of our cruise started with a northwesterly directed transit. To follow the originally planned seismic profiles we would have had to cross an ice field of approximately 20 nautical miles.


PS115.1 - Weekly report no. 2 | 13.08. - 19.08.2018

Geophysics in the fog and an exciting sediment core

[20. August 2018] 

In week two of our four weeks of expedition we have continued our reflexion seismic work in the Northern Greenland Sea.
